AUTOMATIC FAN.

SPECIFICATION forming part of Letters Patent No. 337,587, dated March 9, 1886.

Application filed October 1, 1884. Serial No. 144,437. (No model.)

To all whom, it may concern:

Be it known that I, JAMES MCKINSEY JoHNs, a citizen of the United States, residing at Glenmore, in the county ot' Ware and State ot' Georgia, have invented certain new and useful Improvements in Automatic Fans, of which the following is a description.

rIhis invention relates to that class of devices used to circulate air in houses by automatic action of fans; and it has for its object to fan the air fast or slow, high or low, and to locate the fan on any convenient structure or article of furniture where a current of air is desired.

To this end my invention consists in the construction and combination of parts forming an automatic fan hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure l is a front elevation of my invention at rest in an upright position, and Fig.`2 is a side elevation of the same in position for service.

A represents a fan adj ustably secured upon apendulum-rod, B, which is hung in a box, O, to be swung to and-fro by a crank, D, operated by clock-work F, and connected with the upper end ot' the rod by a link, E. The i'an A is secured to the rod B by a bindingstrap, G, which may beset with screws to hold by friction to the rod at any point along the saine.

HH are two other fans iirinly secured at the ends of arms I, which arms are pivoted at J to the rod B, to spread the fans, as shown in Fig. 2, or to bring them together, as shown in dotted lines. These fans H are connected with the central fan, A, by means of bracinglinks K, so that if the central fan be raised it spreads and raises the side l'ans, and the friction-strap G,holding to the rod B, temporarily secures all the fans at any height required.

The box L,containing the clock-work which operates the fan, is hung to rock upon pivots M in a bracket, N, which is iu turn hinged at 45 Q in a base-piece, O, which is provided with holes and screws P,to secure it to any article of furniture or to any fixture ot' a house. This base may be fixed either on the top or on the side of any sufficiently stable object to sup-` 5o port it, and the bracket is adapted to be swung therefrom into ahorizontal position by means ofits hinge Q, and the box O rocks on its pivots M,to permit the fans to hang down ward. The pivots M are set-screws adapted 55 to bind the box to the bracket in any position.

When the fans are set high up on the pendulum-rod,their stroke is shortened and quickened, and Vice versa. The clockwork may 6o be run by a spring, a weight, or any other motive power.

What I claim as myinvention, and desire to secure by Letters Patent, is-

l. The combination, with clock -woi-k, a 65 pendulum rod caused to oscillate thereby, and a central fan adj ustably xed on the pendulum-rod, of two side fans hung by arms pivoted to` the pendulum rod and two bracelinks connecting the side fans with the central 7o fan, substantially as shown and described.

2. The combination, with a fan hung upon a pendulum-rod and clock-work to cause the said rod to oscillate, of a box to hold the clock-work, the double-branched or bi furcated 7 5 bracket-arms N, having pivotal screws M M, sustaining the box between said arms, and a base-piece supporting the bracket-arm by a hinge, the base-piece being provided with screw-holes and screws, substantially` as shown 8o and described.
